A large amount of dust will be generated during polishing, which is suspended in the air and can easily be inhaled by the human body, causing harm, and the working environment of the staff is poor.

The air passes through the filter and is discharged from the air outlet. The user can open the ash cleaning port to clean the collected dust. Absorbing the dust generated by polishing can reduce the dust suspended in the surrounding air, reduce the dust inhaled by the human body, and improve the working environment.
